I believe you want to add another pipe and use Format-table. You can use -autosize to autosize the columns and if columns get cut off you can add -wrap to have the columns wrap to the next line.
See example:
PS C:\temp\openssh\bin> get-navfiler | select name,status,ipspace,vfnetcount,vfstorecount,adminhost
Name : vfiler0
Status : running
Ipspace : default-ipspace
VfNetCount : 3
VfStoreCount : 1
AdminHost :
PS C:\temp\openssh\bin> get-navfiler | select name,status,ipspace,vfnetcount,vfstorecount,adminhost | format-table -autosize -wrap
Name Status Ipspace VfNetCount VfStoreCount AdminHost
---- ------ ------- ---------- ------------ ---------
vfiler0 running default-ipspace 3 1
